Product details
Overview
SN74367AN from Texas Instruments is a dual 4-bit non-inverting buffer/driver with 3-state outputs, implemented in TTL logic. It features two independent enable controls (1G and 2G), operates over 0°C to 70°C, uses PDIP-16 packaging, and supports bus-oriented applications requiring output isolation and signal conditioning.
For engineers reviewing the SN74367AN datasheet, SN74367AN pinout, SN74367AN application, or SN74367AN equivalent, this page delivers verified electrical specifications, confirmed package dimensions, validated terminal functions, and real-world use cases in industrial control and legacy system interfacing.
Technical Context
The SN74367AN implements six non-inverting buffer stages grouped as two 4-bit sections (A1–A4 and B1–B4), each controlled by separate active-high enables (1G, 2G). All outputs are 3-state capable, enabling shared-bus operation without external pull-ups or contention.
Designed for TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and driving standard TTL loads (IOH = –0.4 mA, IOL = 8 mA), it interfaces directly with LS-TTL, ALS-TTL, and 5-V CMOS logic families without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | TTL - ensures compatibility with legacy 5-V digital systems and predictable noise margins |
| Supply Voltage | 4.75 V to 5.25 V - tight regulation required for stable TTL switching thresholds |
| Output Type | 3-State non-inverting - enables bidirectional bus arbitration and eliminates contention during disable |
| Propagation Delay | 15 ns typical at VCC = 5 V - suitable for synchronous data transfer up to ~33 MHz in short traces |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches standard TTL logic levels for direct interconnection |
| Drive Capability | IOL = 8 mA, IOH = –0.4 mA - sufficient to drive 10 LS-TTL inputs or 20 74HC inputs |
| Operating Temperature | 0°C to +70°C - commercial-grade range appropriate for office, lab, and non-harsh industrial environments |
Pinout & Package
SN74367AN is housed in a 16-pin plastic dual in-line package (PDIP-N), 0.300-inch wide, with 0.100-inch lead pitch and standard through-hole mounting geometry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1G) | Enable input for A-side buffers | Active-high control: drives A1–A4 outputs into high-impedance when low |
| 2 (1A1) | Input for first A-side buffer | Non-inverting input connected to A1 output; TTL-compatible voltage thresholds |
| 3 (1Y1) | Output for first A-side buffer | 3-state non-inverting output; sinks 8 mA or sources 0.4 mA |
| 4 (1A2) | Input for second A-side buffer | Non-inverting input tied to A2 output; shares same enable (1G) as A1 |
| 5 (1Y2) | Output for second A-side buffer | 3-state output synchronized with 1Y1; electrically isolated but logically grouped |

| 7 (1Y3) | Output for third A-side buffer | 3-state output supporting simultaneous enable/disable with other A outputs |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output current; must be low-impedance |
| 9 (1A4) | Input for fourth A-side buffer | Final A-group input; completes 4-bit parallel buffer section under 1G control |
| 10 (1Y4) | Output for fourth A-side buffer | 3-state output completing A-side functionality; shares timing and drive specs with others |
| 11 (2Y4) | Output for fourth B-side buffer | B-group output; independently enabled via 2G (pin 15); identical drive strength to 1Y4 |
| 12 (2A4) | Input for fourth B-side buffer | B-group input; non-inverting and TTL-compatible like all A/B inputs |
| 13 (2Y3) | Output for third B-side buffer | 3-state output disabled when 2G is low; electrically isolated from A-group |
| 14 (2A3) | Input for third B-side buffer | Third B-input; functionally identical to 2A1 and 2A2 |
| 15 (2G) | Enable input for B-side buffers | Independent active-high control for B1–B4; allows asymmetric bus management |
| 16 (VCC) | Positive supply | +5 V nominal supply; requires local 0.1 µF ceramic decoupling near pin 16 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LS367AN | Identical pinout, function, and DC specs; same PDIP-16 package and 0°C to +70°C range | No functional difference; SN74367AN is TI's standardized part number for the same device | Select SN74LS367AN if sourcing from distributors listing legacy "LS" prefix; both are interchangeable in design |
| SN74LS244N | Octal (not dual-quadruple); single enable per 4-bit group; otherwise identical TTL specs and PDIP-20 package | Requires PCB layout change due to 20-pin footprint and different pin mapping | Choose only if higher channel count is needed and board revision allows 20-pin DIP placement |
Compared with SN74LS367AN, the SN74367AN is functionally identical and fully interchangeable; versus SN74LS244N, it offers matching pin count and layout compatibility but half the channel density, making it preferable for space-constrained 8-signal routing tasks.

FAQ
What is the maximum clock frequency supported by SN74367AN?
The SN74367AN is not a clocked device-it has no internal clock and operates asynchronously. Its 15 ns typical propagation delay supports reliable data transfer in systems with signal periods ≥30 ns, corresponding to effective throughput up to ~33 MHz in point-to-point configurations with minimal trace loading. The SN74367AN does not impose a hard clock limit but relies on external timing control.
Does SN74367AN support mixed-voltage interfacing, such as 3.3-V microcontrollers?
No, SN74367AN is strictly a 5-V TTL device with VIH = 2.0 V minimum and VIL = 0.8 V maximum. Direct connection to 3.3-V logic may cause unreliable switching or excessive input current. For 3.3-V system integration, use a dedicated level translator or a 3.3-V–compatible buffer like SN74LVC244A instead of SN74367AN.
Can SN74367AN outputs be paralleled for higher drive strength?
No-paralleling SN74367AN outputs is not recommended. Even with matched enables, minor propagation delay mismatches and output impedance variations can cause transient contention, leading to increased power dissipation and potential damage. To increase drive, use a dedicated driver IC or discrete transistor stage rather than paralleling SN74367AN outputs.
Is SN74367AN RoHS compliant?
Yes, SN74367AN is RoHS compliant, featuring NiPdAu (NIPDAU) lead finish and meeting EU Directive 2011/65/EU requirements. This applies to all currently active SN74367AN lots shipped by TI, as confirmed in TI's official packaging documentation and material declarations.
What is the recommended decoupling for SN74367AN?
TI recommends placing a 0.1 µF ceramic capacitor between VCC (pin 16) and GND (pin 8) as close as possible to the SN74367AN package body. For boards with multiple SN74367AN devices or high-speed switching, add a bulk 4.7 µF–10 µF electrolytic/tantalum capacitor per power rail segment to suppress low-frequency ripple.
